Touchpad goes berserk when I slide finger to the right (2/3 of the way

Hey everyone,

I have a surface laptop 7 and my touchpad is going crazy. I was recently proposed by a pop-up window to select the division between touchpad that would be dedicated to right click only. I decided to try it out thinking I could just change it afterwards, but now it seems like there is no option to change it back. The division is causing all sort of problems, like my mouse goes all over the place when I pass this division line, and the touchpad becomes stiff on the click and starts to click and move everywhere sporadically. I don't find any place where the division line can be set back to normal. The device driver is up to date. The option to divide the touchpad area is no longer available anywhere I've looked. I wonder if it was a new function added to windows 11 which then got removed after another update. Otherwise, this could also mean the touchpad is defective and needs replacement, but there seems to be no touchpad available for replacement on the iFixit site.

Any help or recommandations for troubleshooting would be greatly appreciated.

Thanks,
